Solana基础 - 如何发送代币

使用代币程序转移 SPL 代币。为了发送 SPL 代币，您需要知道其 SPL 代币账户地址。您可以使用以下示例获取地址并发送代币。

import {
  Connection,
  clusterApiUrl,
  Keypair,
  LAMPORTS_PER_SOL,
  Transaction,
  sendAndConfirmTransaction,
} from "@solana/web3.js";
import {
  createMint,
  getOrCreateAssociatedTokenAccount,
  mintTo,
  createTransferInstruction,
} from "@solana/spl-token";

(async () => {
  // Connect to cluster
  const connection = new Connection(clusterApiUrl("devnet"), "confirmed");

  // Generate a new wallet keypair and airdrop SOL
  const fromWallet = Keypair.generate();
  const fromAirdropSignature = await connection.requestAirdrop(
    fromWallet.publicKey,
    LAMPORTS_PER_SOL,
  );
  // Wait for airdrop confirmation
  await connection.confirmTransaction(fromAirdropSignature);

  // Generate a new wallet to receive newly minted token
  const toWallet = Keypair.generate();

  // Create new token mint
  const mint = await createMint(
    connection,
    fromWallet,
    fromWallet.publicKey,
    null,
    9,
  );

  // Get the token account of the fromWallet Solana address, if it does not exist, create it
  const fromTokenAccount = await getOrCreateAssociatedTokenAccount(
    connection,
    fromWallet,
    mint,
    fromWallet.publicKey,
  );

  //get the token account of the toWallet Solana address, if it does not exist, create it
  const toTokenAccount = await getOrCreateAssociatedTokenAccount(
    connection,
    fromWallet,
    mint,
    toWallet.publicKey,
  );

  // Minting 1 new token to the "fromTokenAccount" account we just returned/created
  await mintTo(
    connection,
    fromWallet,
    mint,
    fromTokenAccount.address,
    fromWallet.publicKey,
    1000000000, // it's 1 token, but in lamports
    [],
  );

  // Add token transfer instructions to transaction
  const transaction = new Transaction().add(
    createTransferInstruction(
      fromTokenAccount.address,
      toTokenAccount.address,
      fromWallet.publicKey,
      1,
    ),
  );

  // Sign transaction, broadcast, and confirm
  await sendAndConfirmTransaction(connection, transaction, [fromWallet]);
})();
